refactor(nvim): restructure plugin configs, fix OSV launch port

- rewrite the file headers as block comments and regroup the
  autocompletion and dap files into Settings / Autocommands / Keymaps
  sections
- fix `OSVLaunch`: `dap.configurations.lua.port` was nil (the field is
  a list), so the server ignored 8086; share an `OSV_PORT` constant
  between the launch call and the attach configuration
- `.luarc.json`: list each plugin directory explicitly so lua_ls loads
  their type annotations
- use `vim.fs.basename` instead of `vim.fn.fnamemodify(…, ":t")`
